The church has a Baroque main façade (begun in 1606, with the upper part finished in 1961[4]), preceded by a large staircase completed in 1607.

Other exterior features include the Gothic portal of St. Michael, on the northern façade, and the southern portico of the Apostles, from the 14th century.

The latter originally featured sculptures of the Twelve Apostles, executed by Antoni Claperós in the 1460s, which have mostly been lost, aside from two depicting St. Peter and St. Paul, now in the church's chapter house.

Begun in the early 11th century, it has a square plan with six levels separated by friezes with Lombard bands and double mullioned windows.

The upper reaches of the wall bear a large central rose window (1705, dedicated to the Archangel St. Michael) flanked by two smaller ones.

The Romanesque cloister is notable, featuring a series of columns with sculpted capitals: they depict fantastic figures and animals, and vegetable motifs.

The cloister's galleries are home to numerous tombs of rich members of the monastery, dating to the 14th to 18th centuries, one also by Master Bartomeu (1273).

HBO filmed outdoor scenes for season 6 of its fantasy television series Game of Thrones at the cathedral and its steps.
